Overview

ISO34-1 right angle non notched cutting knife die: ASTM D624 and ISO 34-1 are two rubber tear strength testing methods corresponding to American and international standards, respectively. Although both contain "right angle" tear specimens and are almost identical in external dimensions, they have a core and crucial difference in the depth of the specimen's incision.

💡ISO34-1 Right angle seamless cutting knife dieKey Differences Interpretation and Application Suggestions

Core difference: incision depthAs mentioned above, this is the most fundamental difference between the two. The cut depth of ASTM D624 Die C is variable, while the cut depth of ISO 34-1 Type B is fixed at 1.0 mmASTM D624 Type B (Bow)It has the same shape as the ISO 34-1 standard specimen, but the difference in incision depth also exists: ASTM is 0.5mm, ISO is 1.0mm. This means that even if the appearance is similar, the test results of the two cannot be directly equivalent.
The relationship between the appearance of the sampleIt should be noted that although both are called "right angle type", Die C (right angle type) and Die B (bow type) under ASTM D624 standard are related to the specimens of ISO 34-1. among which,The B-type (right angle) specimen of ISO 34-1 and Die C (right angle) specimen of ASTM D624 are identical in appearanceButThe die B (bow) specimen of ASTM D624 has the same shape as the specimen of ISO 34-1.
How to choose：

If your testing needs to be strictly followedISO 34-1Or national standardGB/T 529So we must chooseB-type right angle cutting knife with a fixed incision depth of 1.0 mm.
If your testing followsASTM D624And it is necessary to perform Die C testing. You need to choose whether to use it according to specific testing requirementsMold without incisionOr is it optionalAdjustable incision depth mold.

To summarize:The ASTM D624 Die C and ISO 34-1 B-type right angle cutting knives have the same external dimensions (31.7 × 100mm), but the former has a variable cutting depth, while the latter has a strictly fixed cutting depth of 1.0mm. This is the core difference between the two and the key to ensuring that the test results meet the corresponding standards.
